THE

-FlR EPLACE-STOVEL E-PECIFICATION forming part of Letters Patent No. 508,341, dated November 7, 1893.

Application filed February 2 8, 1393. Serial No. 464,000., (No model.)

T at whom it may concern.- i Be it known that I, THoMAs I. RAN IN, a citizen of the United States, residing in Philadelphia, Pennsylvania,.have invented certain Improvements in Fireplace-Stoves, of which the following is a specification.

The-object of myinvention is to so construct a fire place stove that the dust flue will be within the limit of the stove casing, and the apron around the hearth can be removed so as to clean under the hearth, as fully described hereinafter, reference being had to the accompanying drawings, in Which Figure 1, is a front view of my improved fire place stove. Fig. 2, is a vertical section. Fig. 3, is a sectional plan view; and Fig. 4, is an enlarged perspective view of a portion of the hearth and apron, showing the apron'detached.

Stoves of. the class shown in the drawings are intended to be inserted into fire place openings, to take the place of the ordinary open grates which are built-in the fire place. These stoves are set up and completedzbefore they are inserted into the fire place, and they simply have to be connected with the flue.

It has been the endeavor of manufacturers to economize in space, especially in depth, and yet have sufficient grate surface without projecting the stove into the room, and further these stoves have raised hearths under which dust and dirt will accumulate, and as ordinarily made the aprons of the hearth are either rigidly secured to the hearth, or are set first and the hearth placed upon them, so that it is impossible to clean the space 'under the hearth without removing the stove.

Referring to the drawings,A is the outer frame of the stove adapted to rest against the jamb of ,thefire place opening, and is secured to the body portion B in any suitable manner. This body portion is adapted to fit in the fire place opening as shown by dotted lines in Fig.

3, and I so arrange it that the back will rest against the back of the fire place, thus utilizing the full opening for grate surface;

0 is the grate which may be of any form desired. 1 have shownin the drawings a tilting grate.

D is the front of thefire box, and the back lofthe fire box has a fire brick lining E, and side brick lining E.

F isthe ash-pit formed by depressing a portion of the.hearth G, and extends under the grate to the'rear of the stove.

As shown in Figs. 2 and 3, I cut a vertical groove in the fire brick E, and secure to the back of the body portion B a flanged plate It forming a dust flue H within the body portion, so that the body portion can rest directly against the back of thefire place and thereby increase the grate surface. This plate It extends up into the flue I above the deflecting brick L', and is provided with a damper J attached to an operating rod j,which when drawn out, turns the damper so as to open the flue, and thus allows the dust from the ashes when the fire is being raked, to v pass up the dusty flue instead of through thefire and into the room. The flue I communicates with the chimney through the passage 2'. The usual blower is used, and the usual ash pit cover is also used, which can be removed bodily from the stove or pivoted in the usual manner.

The hearth G is raised a certain distance above the floor level to give the ash pit sufficient depth, and to allow for the free circula-' tion of air between the stove and the wall of the fire place, and in order to properly finish the hearth an apron or filling plate K extends from the hearth to the floor, and as this apron must have openings for the passage of air, dust and dirt will accumulate underthe hearth, and as heretofore made, these aprons are permanently'secured to or form part of the hearth, they cannot be removed without drawing the stove out of the fire place.

, As shown in Fig.4, I form a depressed rib or flange g onthe edge of the hearth G, and cast on this flange, pins g, at intervals.

Onthe upper edge of the apron'K is an in ternal flange in having openings is adapted to the pins, so that when the apron is placed over the flange on the hearth, the pins will pass into the openings and hold the apron in place. The apron may be made in two parts as shown in Fig. 1, and the parts may be secured together by' a plate shown bydotted under the hearth can be cleaned when the room is cleaned, and replaced without-movin g the stove.

I claim as my invention- 1. The combination in a fire place stove, of the body portion, frame and hearth, witha dust flue formed on the inside of the body portion at the back, a metal casing surrounding the body portion, and communicating at its lower end with the ash pit, and at its upper end with the smoke flue, substantially as described.

2. The combination ina fire place stove, of i the body portion, a plate secured to theinside of the body portion and forming a dust flue within the furnace body, the fire brick having a vertical channel at the back forthe said flue, the lower portion of thefluecommunicating with the ash pit andtheupper ,portion-with the smoke flue, substantially as described.

3. The combination ina fire place stove, of the body portion formed of a-metal casing adapted to rest against thezrear wall of the fire place opening, aframe and hearth-seen red thereto,a grate dividing the ash pit from the fire box, fire brick at the back and sides of the fire box resting against the metal casing,

the rear firebrick being cut away forminga,

channel, avertical flange plate secured'to the inner side of the metal casing at the back forming a dust fine, the lower portion of said flue communi ating with the ash pit, and the upper portion communicating with the smoke :flue,with adamperin-theupper portion, a rod for said damper extending through the frame andsupported thereby, substantially as described.

4. The combination in a fire place stove, of

the elevated'hearth, adepressed ashpitformed stantiallyas described.

6. The combinatiomimanopeuifireplace, 0f theelevated shearth Gr, haviinga depressed flangeg, ,pinsig" OilsSfllflififitlgB with an apron K having an internal :fiange kiat ;its upper.

edge,with openings kain said flangeintowhich the pins extend wsrhen the apron-is mounted ,upon the hearth, substantially as described. In testimony whereof I :have signed my name to this specification in the presence of two subscribing witnesses.
